Description V P 2007-10-09 01:26:44 UTC

Hi,

I own a 945GM and I'm using the intel driver on xorg 7.2 as provided by Mandriva 2008.0 . Randr extensions 1.2 are included in the package. After I boot, when I plug my TV cable on the laptop TVout, I get a picture on the screen but it's black and white.

I've seen several people on the internet having the same problem and they were told to change their PAL settings, like in this page : http://www.intel.com/support/graphics/sb/CS-006338.htm. But how can I do this with the intel driver ? The documentation doesn't mention it.

If it can help, I'm living in Belgium, so I understood I should use PAL-H according to this gentoo tutorial : http://gentoo-wiki.com/HOWTO_TV-Out.

To change to PAL, you can do sth. like:
xrandr --output TV --set TV_FORMAT PAL --mode 800x600

btw, I can see colorful TV on intel driver with both PAL and NTSC.

Yes ! thanks. It works fine.

xrandr --output TV --set TV_FORMAT PAL --mode 1024x768 is working for me. Can't xrandr automatically detect the output is PAL ?

Good to know this. So I'm closing this bug.

I don't think current xrandr can detect PAL. Keith, please correct me if I'm wrong. btw, can we add an option to set PAL in xorg.conf, so PAL users can be more confortable?

In the TV monitor section, add 

  option "TV Format" "PAL"
